I then till the spaces with sawdust, tan-bark, or other suitable fibrous material, to the depth of about o ne-third the length of the blocks. This material, absorbing part of the coal-tar which has been spread upon the oorin g, will prevent the sand and gravel from Working under the ends of the blocks, and thus rendering thesurface uneven.
